The quantity to be made use of, is one ounce of tobacco to one gallon of water, with about two handfuls of elder. You may, however, make it as strong as you please, it being perfectly innocent to the plants.
1052. To destroy Insects prejudicial to Apple-Trees.—To one hundred gallons of human urine, and one bushel of lime, add cow-dung to bring it to the consistence of paint. With this composition anoint the trees. The month of March is the proper season for applying it. If the white efflorescence-like substance in which the insects are lodged, has made its appearance, it should previously be brushed off.
1053. To destroy wasps on Fruit-Trees.—Wasps, about the month of July, will begin to swarm about the early fruits; and for their destruction, phials should be hung about the branches, half-filled with honey and water, or with sugar and small-beer. These should be emptied and replaced once in two or three days, otherwise they do not take so well—these little animals being extremely sagacious, and disliking the appearance of their own species, when dead.
1054. Another.—Winter is the proper season to apply the following solution. The juices are then determined to the root.
Soft soap, two pounds; leaf or roll tobacco, one pound; nux-vomica, two ounces; and turpentine, half an English gill: boil them in eight English gallons of soft or river water, to six; and use it milk-warm.
Unnail or untie all the branches from the wall or trellis; brush every part of the tree clean with a soft brush, such as is used for painting; then, with a sponge, carefully anoint every branch, root, and bud; and be sure to rub it well into every joint, hole, and angle, as it is there the eggs or larvæ of the insects are chiefly lodged. The rails, spars, &c., of the espalier or trellis, should also be anointed as above.
